7.5  "Cam disk" - Technology DB 
The DB is described in the integrated technology section and is read-only in the 
STEP 7 user program. 
The DB is non-retentive, irrespective of the retentivity setting of the CPU. 
Variable ErrorID 
Shows the ErrorID of the last error or warning detected at the cam disk. 
An error message can be acknowledged by calling FB 402 "MC_RESET" 
(with Axis = number of the technology DB). 
Variable ErrorBuffer[0..2] 
Buffer for the first three errors and warnings. The first error is written to ARRAY 
element 0, the second to ARRAY element 1, etc. 
This content of the buffer can be cleared by calling FB 402 "MC_RESET" 
(with Axis = number of the technology DB). 
Variable Status 
Value Function  Comments 
0  Cleared  The cam does not have interpolation points or segments. 
1 Added interpolation 
points / segments 
The cam contains interpolation points / segments. 
2  Interpolated  The cam is interpolated (i.e. it is suitable for synchronous operation.) 
3  Error  An error has occurred 
Variable UserCount 
Indicates how many technology objects are currently using the cam.
